TCPTester is a load/performance testing tool which sends the testing messages (requests) as byte arrays over the net by tcp protocol. The destination of these messages is an Application accessed by means of a host: port pair. Parameter host is a character name of server not an ip address. Scenario file (scenario.ini) describes a number of established connections, requests intensity, starting delay, time of a testing for every testing message.
This tool differs from famous products like IBM (Rational) and HP (Mercury) in a way that it isn't based on traffic produced by User's GUI but it sends the messages (requests) of special format over the net (tcp) connections. One should describe the messages (requests) manually based on understanding of tested software application. These message descriptions should be saved in xml files. This tool seems to be useful in cases when the testing load should be generated not from User's workstation but from, say, one software application component to another software application component. In this case we are able to simulate sending of (N) requests per time over (L) tcp connections.
